This reply is referring back to the unidentified track photos 1/3 of the way down the 4th page of this thread. IMG_1661.JPG, IMG_1669.JPG & IMG_1673.JPG.

First photo: This is a bounding animal because there are two tracks on the outside, and two tracks a little behind and on the inside. The fronts
land out and forward, usually parallel each other, and the hinds land inside and to the rear, usually staggered. You can tell they're rodent tracks because the front tracks (to the rear and center of the track group) have four toes each, while the hind tracks (to the front and outer edges of the track group) have five toes each. This toe pattern is only found in rodents. Then you can tell it's a squirrel because of size and general toe/heel pad shape. Finally it's a ground squirrel because the front tracks are asymmetrical and all the toes (front and hind) are curved inward. Folks around here would call it a gopher colloquially, though it's not actually a gopher (family Geomyidae), but a Columbian ground squirrel (family Sciuridae)
The second are chipmunk or mouse on the right (again, the bounding pattern tells us which tracks are front and hind, and the different toe counts between front/hind ID it as a rodent. Size, location and specific toe/heel pad shapes ID the species). The leftmost tracks are paired, as if the animal was bipedally hopping, and only have four toes (three in front and one behind) and therefore are a small ground-feeding bird, probably a sparrow or junco.
The third are really cool! These are very small tracks (about one inch wide), with no discernible pad, covered in fur (you can see the impression in the mud), very deep gripping claws, four toes and a lot of asymmetry in the toes. The outermost toes are much further toward the rear than the innermost toes. With this much asymmetry, and no discernible pad, just fur, it can't be a canid like a fox or coyote. Red foxes do have furry feet but they're much bigger and have generally symmetrical feet. The only thing this could be, in my understanding, is the paired front feet of a cottontail rabbit in a bound.
